Fertilizer use in Thailand has become an integral part of agriculture due to the declining availability of arable land and the increasing role of rice and other agricultural exports in the economy. Approximately 47 percent fertilizer is used on rice, production of which has increased from 13.4 million MT to 36 million MT from 1970 to 2010 coinciding with a rise in fertilizer consumption from .2 million MT to 2.6 million MT.
The agricultural sector plays a crucial role in Cambodia’s economy, and accounts for approximately 27.3 percent of GDP. Crop cultiva-tion on Cambodia’s 4 million ha of agricultural land has become more challenging with each passing year due to low soil fertility (White et al., 1997). Fertilizer application is crucial for nutrient replenishment, increased crop yield and elevated crop biomass which is necessary for moisture retention and nutrient efficiency (Bumb, 1996).
The Philippines is an island nation, comprised of 7,107 islands that are split into 3 geographical divisions: Luzon, Visayas, and Mindanao. In 2013, agriculture contributed 10.45 percent to GDP (PSA-NSCB, 2014) and 31 percent to employment (PSA-BLES, 2014). More im-portantly, its contribution to national and household food security is significant. Cereal production increased from 7.6 million tons in 1970 to 22.1 million tons in 2010. During the same period, fertilizer use increased from 201,000 nutrient tons to 771,000 nutrient tons (FAOSTAT).
Indonesia is an archipelago consisting of 13,466 islands, which are divided into 33 provinces. Java, Bali, and Nusa Tenggara are the inner islands and contain 62 percent of the total population of 246 million, but only accounts for 8 percent of the total land area. The inner islands are naturally more fertile than the outer islands that have nutrient-poor, acidic soils. In theory, fertilizer use should be higher on the outer islands, but in reality outer island fertilizer use is generally lower, making crop yields lower, especially when compared to Java.
This paper provides the history of development; an analysis of the current industry’s structure, conduct, and performance; and a review of related regulations of the maize seed industry in Thailand. The lessons learned from the success of the maize seed industry in Thailand could provide implications for the development of the seed industry in other developing countries
Factsheet
Rapid population growth in many developing countries has raised concerns regarding food security and household welfare. To understand the consequences of population growth on in the general equilibrium setting, we examine the dynamics of population density and its impacts on household outcomes using panel data from Indonesia. More specifically we explicitly highlight the importance of migration to urban sectors in the analysis. Empirical results show that human capital in the household determines the effect of increased population density on per capita household consumption expenditure.
Although agriculture only contributes 20 percent to GDP in Vietnam, over 70 percent of the population relies on the sector. Rice is the most important crop in Vietnam accounting for 90 percent of total grain output. The agricultural sector has faced recent challenges due to urbanization and industrialization, as well as few opportunities for increasing cultivated land area. Increased crop yields through the use of chemical fertilizer is one of the few methods available for increasing agricultural output.
This policy brief will provide an analysis of the maize seed industry’s current state and future prospects, prefacing that with a review of the historical context under which it emerged. Lessons learned from this sector could have implications for the development of the seed industry in other developing countries.
